The system is implemented mainly for the paralyzed persons. The system helps the disabled persons to move independently. The system consists of a wheelchair, RF modem and a PC, which is connected to a webcam[12]. User’s eye movements are converted to screen position using matlab software. When user looks at appropriate direction, using some image processing techniques the computer system will detect the direction, based on the coordinate position of centre of the iris[1] i.e., when user moves his eyes balls up then move forward, left then move left, right then move right, down then move backward and in all other cases wheel chair will stop[16]. The series of images captured by the camera is being processed and then it is fed to the RF modem. The RF transmitter transmits the processed data and it is received by the RF receiver on the wheelchair part. The decoder decodes the data and feds to the microcontroller. The microcontroller will produce the corresponding control information for the wheelchair motors. Ultrasonic sensors are connected to the microcontroller to detect the static and moving obstacle on the path of the wheelchair. The wheelchair consists of four Š 2017, IRJET

wheels, two front wheels and two rear wheels. The front wheels helps to steering left and right and the forward movement is controlled by the rear wheels. Key words: MATLAB, ATMega328, RF module 1. INTRODUCTION The Wheelchair is dependent system used by elderly and physically disabled persons. Here the implemented system is a totally independent eye controlled electric wheelchair[2]. As per requirement of the disabilities, different kind of automatic systems are available in market such as voice control or joystick control system. Considering the totally paralysed persons, they feel some difficulty to use that type of systems. Here the Eye controlled system make their life easy and more convenient. In this system, the Camera captures a continues series of images in real time and do some image processing techniques like binarisation and edge detection then the processed image is then send to the RF modem as a serial data[1]. The RF transmitter encodes the data and send to the wheelchair. In the wheelchair part, the RF receiver receives the data and decodes it. This |
